Quick Summary

Dissolution is the process where a solute disperses into a solvent to form a homogeneous solution. This can involve solids dissolving in liquids, liquids in liquids, or gases in liquids. The solubility, or the degree to which a substance dissolves, depends on the chemical nature of the substances involved, temperature, and sometimes pressure. Generally, solubility of solids in liquids increases with temperature, while gas solubility decreases with temperature but increases with pressure. Henry's law states that the amount of gas dissolved in a liquid is proportional to the pressure of the gas above the liquid. "Like dissolves like" is a common principle, meaning similar substances tend to dissolve in each other.1234

Solubilities of solids and gases
Since the dissolution of one substance in another can occur only if there is a decrease in the Gibbs energy, it follows that, generally speaking, gases and solids do not dissolve in liquids as readily as do other liquids. To understand this, the dissolution of a solid…
